Seachem Matrix (1L/2L/4L)


Seachem Matrix is a great filter media. It is created from natural, porous rock.

Due to its large surface area, just 2L of Seachem Matrix is enough to provide space for enough bacteria for an aquarium of 1600L+ in volume.

Seachem Matrix provides internal space where anaerobic bacteria may live. We are currently testing its effects on Nitrate but it has been well tested on Ammonia and Nitrite with excellent results!

SKU: B0002A5VIY Categories: ,


  • High capacity bio filtration
  • Controls ammonia, nitrite, and nitrate
  • Supports aerobic and anaerobic bacteria species


Use 250 mL of Matrix for each 200 L (50 US gallons) of water.

Matrix may be placed in any kind of filter, and is particularly effective in a canister filter.

Matrix is sufficiently large that no filter bag should be required for most applications. Matrix works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications.

Use with Stability to more rapidly establish the bio-filter. This dosage may differ from your packaging. Based on updated studies, we’ve found Matrix treats even more water than previously asserted.
